### コールバックのパス式 { #the-callback-path-expression }

コールバックの *パス* には、*あなたの API* に送られた元のリクエストの一部を含められる [OpenAPI 3 の式](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)を使用できます。

この例では、`str` は次のとおりです:

```Python
"{$callback_url}/invoices/{$request.body.id}"

            .header("Upgrade", "websocket")
            .header("Sec-WebSocket-Key", "abc123")
            .build(),
        ).execute()
    response.body.close()
    networkLogs
      .assertLogEqual("--> GET $url http/1.1")
      .assertLogEqual("Connection: Upgrade")
      .assertLogEqual("Upgrade: websocket")
      .assertLogEqual("Sec-WebSocket-Key: abc123")
      .assertLogEqual("Host: $host")

        assertEquals(oomCause, oomException.getCause());
    }

    @Test
    public void test_messageCodeWithPropertyKey() {
        // Setup - test message code with different property keys
        final String message = "Query field error";
        final String propertyKey = "searchQuery";
        final VaMessenger<FessMessages> messageCode = messages -> messages.addErrorsInvalidQueryUnknown(propertyKey);

      const val BOUNCYCASTLE_PROPERTY = "bouncycastle"
      const val LOOM_PROPERTY = "loom"

      /**
       * For whatever reason our BouncyCastle provider doesn't work with ECDSA keys. Just configure it
       * to use RSA-2048 instead.
       *
       * (We otherwise prefer ECDSA because it's faster.)
       */

        secondaryParameterOffset = SECONDARY_PARAMETER_OFFSET;
    }

    @Override
    void reset() {
        super.reset();
        isPrimary = hasMore = true;
    }

    void reset(final int key, final String lastName) {
        reset();
    }

    @Override
    public boolean hasMoreElements() {
        return hasMore;
    }

    @Override
    public Object nextElement() {

Bu durumda, `int` key’lere ve `float` value’lara sahip olduğu sürece herhangi bir `dict` kabul edersiniz:

{* ../../docs_src/body_nested_models/tutorial009_py310.py hl[7] *}

JSON key olarak yalnızca `str` destekler, bunu unutmayın.
